Laser Cutter Engraver - What's Inside

A little bit of almost ancient technology here. We look inside a 40w laser to see how the components work together to engrave and cut.

just a nit in case anyone is confused. The switch you talk about at 14:08 is just a laser on/off switch. The "current" label is for the milliamp meter above the switch. Nice job on the fan ducting.

LOL True, this is confusing. I said current because I am constantly doing the wattage calculation since the tube is rated in watts. I have a 110v system, but they come in other voltages. The switch actually goes to the enable input on the power supply and indirectly cuts the power output to the lasing tube. Thanks for pointing that out.
